For the long term performance stability test, we set the drive up to run a 20-minute 4K random test with a 30% write, 70% read split, at a Queue Depth of 256 over the entire disk. The Optane 900p averaged 140,055 IOPS for the test with a performance stability of 98.6% which is enterprise standard and exceptional for a drive aimed at the high-end desktop/workstation market segment.
